4、结构及工作原理：

Four、Structure and working principle:

     BEd系列电力液压推动器主要由隔爆电机、中间法兰、叶轮、成套活塞等组成。接通推动器电源，电机旋转带动叶轮产生压力油，推动活塞及连杆向上运行。达到预定行程后维持其推力。电源断开，电机及叶轮停止转动不再产生压力油，活塞及连杆在外力作用下恢复原位（见图一）

     Bed series power hydraulic pusher is mainly composed of flameproof motor, composed of intermediate flange, impeller, a complete set of piston. Connect the drive power supply device, the motor rotates and drives the impeller produces oil pressure, promote the piston and connecting rod to run. After reaching the scheduled trip to maintain the thrust. To disconnect the power supply, electric motor and impeller stops rotating no longer produce pressure oil, the piston and connecting rod under the external force recovery in situ (see photo)
